We have our Flannelboard sitting on an "Aluminum Telescoping Easel".

Rather than raise and lower it for different ages, I have a couple small plastic stools handy for when the younger children need one step up to add higher items, like stars, clouds and birds as when we did Creation pictured below.

We have had a Deluxe Bible Set by Betty Lukens for years and all ages enjoy it to this day.

Aluminum Telescoping Easels are expensive, but we've had ours for years and was well worth the cost.

On the stand we keep 4 items handy: first a White Board, and sitting on top of this are our three flannel backgrounds (plain blue, water/sky, and an indoor scene). Whichever scene we need we just move it to the front. It sits in the corner of our Story Table Room and the 2 boxes of flannelgraph people/objects/scenery are stored underneath our Story Table for easy access.

I like to keep it interactive so I lay the story pieces on top of the story table where the students can easily select pieces themselves, as they come up in the story, and place on the flannelboard.

If we need the White Board we simply remove the 3 background scenes and lean them against the wall.

We use the White Board in games to track our scores or for games that involve drawing, like Pictionary.

To create your own flannelgraph background  simply attach a large piece of flannel to a piece of cardboard that you have partially slit so it will fold in half, an easier size if you need to store it elsewhere. Wrap flannel around to back, trim flannel at cardboard bend (see V cuts below), so cardboard will still be able to fold. It's been quite some time since I did this, but I think I also glued the flannel to the cardboard (using white glue) and then used packing tape along the back, as pictured below, surprisingly it has held up well for years.
